     a)   designed such disclosure controls and procedures, or caused such
          disclosure controls and procedures to be designed under our
          supervision, to ensure that material information relating to the
          registrant, a including its consolidated subsidiaries, is made known
          to us by others within those entities, particularly during the period
          in which this report is being prepared; and

          affected, or is reasonably likely to materially affect, the
          registrant's internal controls over financial reporting; and

5.   The registrant's other certifying officers and I have disclosed, based on
     our most recent evaluation of internal controls over financial reporting,
     to the registrant's auditors and the audit committee of registrant's board

     a)   all significant deficiencies and material weaknesses in the design or
          operation of internal controls a over financial reporting which are
          reasonably likely to adversely affect the registrant's ability to
          record, process, summarize and report financial information; and

     b)   any fraud, whether or not material, that involves management or other
          employees who have a significant role in the registrant's internal
